Concrete Sidewalk Building in Diamond Bar CA - a walk that drains away from the house
Cracked, lifted or puddled walkway out front? We build a new concrete sidewalk with a grippy finish that sends water away from the house.

What goes into a new concrete sidewalkin Diamond Bar, from the ground up


If your walk is cracked, lifted by roots or holding puddles, the trouble usually started underneath, in the subgrade, the dirt the slab sits on. At D&T Diamond Bar Concrete we handle concrete sidewalk building in Diamond Bar and the cities around it, and I start every walk with the ground, not the finish.
We dig out topsoil and roots and pack the base hard so the walk is supported evenly from end to end. Before we set the route, I check where it crosses a driveway and where tree roots run. Then we give it a finish with grip for wet days and pitch it so water runs away from the house.
Price moves with the walk's size, how much old concrete gets hauled off, and whether a driveway crossing needs a heavier section. The schedule turns on whether the city wants a permit, which we check before we set a date, and on the time new concrete needs to harden. The estimate spells out what's in the price and what isn't.
You can count on straight answers about the ground under your walk and where the water goes, so call (909) 760-1399.
Concrete sidewalks we build around the house
Sidewalks are flatwork, the flat concrete jobs like driveways and patios, and we build each walk around what it meets. For color or a pattern, see our decorative concrete work.
New walks to the door
We dig out the path, pack the base and pour a walk with a broom finish, a light brushed texture that gives shoes some grip when it's wet.
Driveway crossings
Where cars roll over the walk, that stretch often needs a thicker section with rebar, steel bars inside the concrete that help it carry the weight.
Replacing a broken walk
We break out the old slab, haul it off and fix the base that let it fail. If the walk runs to the garage, we also pour garage floor concrete.

Why Diamond Bar homeowners call D&Tfor sidewalks, steps and driveways
Working with us is plain. You hear the bad news first if there is any, and you get a reason for every part of the price.
The owner on the crew
I don't hand your walk to people you never met. I work alongside our crew on the job, from setting the forms to the last broom pass.
Fully licensed and insured
We carry a license and insurance for the concrete work we do, and you're welcome to ask for proof before you sign anything.
Base first, finish second
The base is the part nobody sees on day one and the first thing people want to cut, but it's what keeps a walk flat, so that's where we spend.
In business since 2023
I ran a warehouse floor for close to twenty years, learned flatwork under a contractor around Diamond Bar, then started our business in 2023.
Satisfaction guaranteed on every job
We'd rather lose a job than sell you more concrete or a fancier finish than your walk actually needs.

Call or send a message
Call (909) 760-1399 or send the form with the walk's rough size, and we get back to you to set a time to look at it.
I walk and measure it
I come out myself, measure the route and check the trees and the driveway. Your estimate spells out what's in it and what isn't, like hauling off old concrete.
Permit check and a date
We settle the permit question with the city, then set a date. Street work needs the city inspector emailed at least 48 hours before starting, or it can be ordered removed and redone.
Dig, form and pour
Our crew packs the base, sets the forms and pours, then cuts control joints, shallow grooves that give the slab a planned place to crack instead of a random one.
Cure, clean up, walk through
We start curing right away, keeping the new concrete damp or covered so it hardens slowly and strong, then clean up and walk the finished sidewalk with you.
Sidewalk questions we get asked
How much does a new concrete sidewalk cost near Diamond Bar?
A concrete sidewalk or walkway in the Los Angeles area usually costs about $5 to $15 per square foot. Where yours falls depends on the size, the tear-out and any driveway crossing we talked about above. I'll measure your walk and write up the estimate.
What causes a concrete sidewalk to crack or lift?
Tree roots and expansive soil, dirt that swells and shrinks, are the usual reasons a sidewalk moves over the years. Sidewalk guidance says picking the route and preparing the ground can matter more than making the concrete stronger, which is why we check for roots before we set the line.
Who can build a concrete sidewalk in California?
A sidewalk is flat concrete work, and California's C-8 concrete contractor license covers people who form, pour, place and finish that kind of work. The small-job exemption only lets an unlicensed person take work under $1,000 when it needs no permit and they employ no one, so a crew with workers needs a license.
Do I need a permit to build a sidewalk in Diamond Bar?
The city decides, and it hasn't settled it in writing for sidewalks. Diamond Bar requires building permits to build, change, remove or repair structures, but its list names things like new buildings, fences and signs, so we check with the building office before we set a date and handle the paperwork with you if one's needed. Work on the public street needs the city's street construction permit, and a dumpster in the street or driveway approach needs an encroachment permit from Diamond Bar City Hall at 21810 Copley Drive. The city's building permits page has the current steps.
How long does a new concrete sidewalk take to cure before sealing?
One concrete supplier's guide says concrete takes at least 28 days after the pour to cure before it's sealed, so sealing is a later step, not a pour-day one. Curing right after the pour can be done with a curing compound, soaking, wet burlap or plastic, or curing paper, and you can ask which one we'll use on your walk.
What is the best way to keep a sidewalk from getting slippery or holding water?
Give it a textured finish and a steady pitch away from the house. Sidewalk guidance warns that a smooth troweled finish can be dangerous when wet, and calls for no low spots that hold water and no slope that sends runoff toward buildings. Ask any contractor, us included, which finish and drainage they plan before the pour.
